LOTION.

SPECIFICATION forming part of Letters Patent No. 792,148, dated June 13,1905.

Application filed March 19, 1904.. Serial No. 199,050.

To all whmn it may concern.-

Be it known that we, Ennns'ro MoNTELnoNE, residing in Jersey City,Hudson county, in the State of New Jersey, and VINCENZO CnsAREo,

residing in the borough of Manhattan, in the city and State of New York,both subjects of the King of Italy, have invented a certain new andImproved Lotion, of which the following is a specification.

I0 It has long been believed by a few in M0- rocco, Africa, that asoluble mineral or stone, known as algazu, found in certain rainlessdistricts of central Africa could be used with advantage in a bath. Ourlotion comprises that material as one of its ingredients.

WV e have discovered that by agitating an excess of algazu in anearly-saturated solution of subborate of soda (borax) and allowing alittle time to elapse such a proportion of the stone may be dissolved orcombined that a slightly-thickened liquid results, which haspeculiarly-valuable qualities when applied eX- ternally as a lotion. Itmay be used freely and never injures the most delicate skin, while 5 itseffects in invigorating and vitalizing the skin are useful in all formsof skin diseases. It diminishes the effects of age by clarifying andtightening the skin.

\Ve have in our experiments introduced a 3 small quantity of almond-oiland believe that this contributes not only to the pleasure of the user,but also in some degree to the beneficial results.

To manufacture our lotion, dissolve in pure 3 5 water, preferablydistilled, a little less borax than it will hold. WVith materials ofordinary quality for one hundred gallons of distilled water introduceone hundred and fifty ounces of subborate of soda. To this nearly-satu-4 rated solution of borax add a little more than fifty ounces of thealgazu in a finely-broken condition. About fifty ounces will bedissolved. Add to the whole twenty-five ounces of the almond-oil andagitate at intervals for a few hours, all at ordinary temperatures.

There should always be an excess of the algazu introduced, so that aresidue remains after the solution is saturated.

The natural product algazu has a local reputation in northwesternAfrica, but has never 5 anywhere been before compounded to constitute anarticle of manufacture. So far as We can learn it has not beforeattracted any attention in the civilized world.

Chemical analysis of algazu shows the following: Silica, (SiO2,) 58.30per cent.; magnesia, (MgO,) sixteen per cent.; oXid of iron, (Ee2O3,)5.25 per cent.; oXid of alumina, (A1203) 5.70 per cent.; potash andsoda, (K20 and Na2O,) 2.10 per cent.; lime, (Oa(),) 1.03 per cent.;moisture, 11.72 per cent.; total, 100.10 per cent. The union of these bythe processes of nature gives important and valuable results whichcannot be attained by 6 art. 5

Modifications may be made Without departing from the principle orsacrificing the advantages of the invention. The temperature at whichthe solution is effected may be increased. The consistency of the lotionmay 7 be increased by evaporation at moderate temperatures, and thusgreater medicinal effects may be obtained from a given quantity of thematerial; but we prefer a consistency about like ordinary olive-oil.

The almond-oil may be applied at any stage with gentle agitation. Thesolution unites permanently with the oil in a little time.

We claim as our invention- 1. The within-described process formanufacturing lotion dissolving boraX in cold water nearly to the pointof saturation subsequently dissolving in such solution to completesaturation the natural substance known as algazu and agitating atintervals for 5 several hours with almond-oil until it is permanentlycombined.

2. A lotion composed of water, borax, algazu and almond-oil, combined asherein specified. 9

In testimony whereof we have signed our names to this specification inthe presence of two witnesses.
